Guess Simulated leather Black Boots with Stretch panels Women’s Size 7.5

These boots are in EUC. They come with the original box. I love the detailing with the silver toned zipper and “G” affixing the cross strap. I also love the quilted back, high-low look and chunky look but the lightweight feel when you’re wearing them. They are clean inside and out without defects. They are a roomy 7.5 allowing socks if desired. I can’t find a materials tag! I thought all shoes were supposed to have them?? Thanks for looking and ask any questions!
